NoiseWorks Audio, the developer behind vocal and dynamics tools like VoiceAssist and DynAssist, has released a targeted, no-cost solution called PloseAssist. Available as a free download for Windows and macOS, the plug-in is engineered to automatically detect plosives and attenuate the low-end thump only during the exact moment a pop occurs, leaving the rest of the vocal performance completely untouched.
Why Traditional Plosive Fixes Fall Short
In a typical home studio or office recording setup, plosives happen when a fast-moving blast of air from consonant sounds hits the microphone capsule directly, usually because of close mic placement or the absence of a physical pop shield. Because that physical impact translates into a massive spike of low-frequency energy, the lazy fix has always been to engage a steep low-cut (high-pass) filter around 100 Hz to 150 Hz.
The problem? Human voices—especially deeper speaking voices, broadcast dialogue, and close-miked vocals—carry their foundational weight in that exact frequency band. Cutting those frequencies permanently across a thirty-minute timeline makes the speaker sound thin and boxy just to fix a few dozen millisecond-long transients. Dynamic equalizers and multiband compressors can help, but they require careful threshold calibration so they do not accidentally clamp down on legitimate low notes when a vocalist or presenter leans into the microphone.
According to NoiseWorks Audio's official documentation, PloseAssist bypasses manual threshold hunting altogether. The plug-in continuously analyzes the incoming audio for the specific acoustic profile of a plosive while ignoring standard low-frequency vocal energy. When a pop is identified, it dynamically ducks frequencies below approximately 250 Hz solely for the duration of that burst. When no plosive is present, the processor stays out of the way, preserving the full body of the original recording.
- Section Summary: PloseAssist replaces static high-pass filtering and tedious manual clip editing with automatic, threshold-free detection that attenuates frequencies below 250 Hz only when a plosive burst is present.
Under the Hood: Controls, Modes, and Latency Specs
While NoiseWorks Audio designed PloseAssist so that its default state handles most speech, dialogue, podcast, voice-over, singing, and rap tracks right out of the box, it is not a "black box" processor that forces you to trust it blindly. As detailed by both NoiseWorks Audio and trade coverage from ProSoundWeb and Production Expert, the interface gives audio engineers straightforward visual and audible verification along with two primary adjustment parameters:
- Amount (0% to 150%): Controls how aggressively each detected pop is attenuated. Users can dial it back below 100% to retain natural articulation on delicate vocal takes, or push it up to 150% for aggressive close-miked recordings.
- Sub (1.00x to 3.00x): Adds deeper attenuation specifically below 100 Hz, where the heaviest physical mic thump resides. Production Expert notes this control is particularly aimed at rap vocals, close proximity mic work, and untreated, boomy rooms.
- Visual Scrolling Display: Every triggered cut is plotted in real time as a red dip on a scrolling timeline alongside a dedicated gain-reduction meter.
- Delta Auditioning: Clicking the Delta button (which illuminates yellow when active) solos only the signal being removed. This allows you to listen specifically for isolated low-end thumps and silence in between, confirming that no actual vocal tone is being shaved off.
Because lookahead detection and low-frequency filtering require processing time, PloseAssist provides two selectable operating modes tailored to different stages of a production workflow. According to specifications reported by ProSoundWeb, both modes report their exact processing delay to the host Digital Audio Workstation (DAW) for automatic delay compensation:
| Processing Mode | Reported Latency | Recommended Use Case | Availability |
|---|---|---|---|
| Low Latency | 17.5 ms | Live tracking and presenter/vocalist monitoring | Included in free PloseAssist |
| Balance | 137.5 ms | Post-production editing and mixing with higher detection accuracy | Included in free PloseAssist |
| HQ 0ms | 0 ms (Pre-analysis) | Offline-style full-track syllable analysis prior to processing | Requires paid VoiceAssist Advanced |
It is worth noting that third mode in the table above. While you will see an HQ 0ms option referenced in the ecosystem, NoiseWorks Audio locks that zero-latency, full-recording pre-analysis mode inside its commercial flagship plug-in, VoiceAssist Advanced (which received the feature via an October 15 update). For users sticking strictly to the free standalone PloseAssist plug-in, Low Latency and Balance are the active workhorses, accompanied by DAW automation support for Amount, Sub, Delta, and Bypass, undo/redo functionality, presets, and a vector UI resizable up to 200%.
- Section Summary: Users can fine-tune plosive reduction using the Amount and Sub controls, verify transparency via the Delta solo button, and switch between a 17.5 ms Low Latency mode for tracking and a 137.5 ms Balance mode for mixing.
Windows Compatibility, Formats, and the "Free" Catch
For Windows PC builders, streamers, and audio engineers, checking host compatibility before cluttering up your VST3 folder is essential. PloseAssist is not a standalone Windows system-tray utility for live Discord or Teams calls out of the box; it is a standard audio plug-in that must be loaded inside a compatible host application or DAW.
According to NoiseWorks Audio's official system requirements, here is what you need to know before installing:
- Windows OS Requirements: 64-bit Windows 10 (version 1909 minimum) or Windows 11.
- Plug-in Formats: VST3 and AAX on Windows (Audio Units is also included for macOS users).
- Supported DAWs & Channel Layouts: Officially tested across major hosts including Reaper, Ableton Live, Cubase, FL Studio, Studio One, Pro Tools, and Reason, supporting mono, stereo, and multichannel tracks up to 7.1 surround.
- macOS Version Note: For cross-platform studio operators running both Windows and Mac machines, PloseAssist runs natively on Intel and Apple Silicon processors, though NoiseWorks Audio's product page lists conflicting minimum OS requirements—stating macOS 12.0 in one specification block and macOS 10.15 in another.
Finally, let us talk about the registration terms, because "free" in the audio plug-in world rarely means an anonymous direct download. To activate PloseAssist, you must provide an email address on the NoiseWorks Audio product page, which automatically enrolls you in the company's marketing newsletter (though you can unsubscribe at any time). NoiseWorks then emails you a free license key. The workstation where you authorize the plug-in must have an active internet connection for activation, and each free license permits a maximum of two concurrent machine activations.
For Windows content creators and engineers who frequently deal with less-than-ideal microphone technique—especially when editing guest audio recorded remotely—trading a newsletter signup for a dedicated, Delta-verifiable de-plosive tool is a very practical bargain. Just remember that no software algorithm defies physics entirely: if a plosive burst physically clips the microphone preamp and distorts the analog-to-digital converter on the way in, even the smartest 250 Hz ducking curve won't un-clip the waveform. Keep a pop filter handy when you can, and let PloseAssist clean up whatever sneaks past it.
- Section Summary: PloseAssist runs as a 64-bit VST3 or AAX plug-in on Windows 10 version 1909 or newer, supports up to 7.1 multichannel tracks, and requires an email newsletter signup plus an internet connection to activate across up to two machines.
